Virtual subscriber identity moduleVirtual subscriber identity module description/claimsThe Patent Description & Claims data below is from USPTO Patent Application 20090125996, Virtual subscriber identity module. Brief Patent Description - Full Patent Description - Patent Application Claims
This application is a continuation in part of U.S. patent application Ser. No. 12/168,791 filed Jul. 7, 2008 which claims the benefit of German Patent Application No. 102007044905.6 filed Sep. 19, 2007. This application is related to wireless communications. With the growing number of wireless communication devices, there is a need to provide a more dynamic solution to the current subscriber identity module (SIM) function carried out within a SIM card or UICC, to overcome some specific shortcomings in relation to modern and evolving mobile communication networks. The UICC provides a secure execution and storage environment from which to execute the SIM authentication algorithms and store credentials. However, the cost of the UICCs, their impractical form factor, and limited functionality prevent them from being used in applications where the mobile network operator may only be known some time after the purchase of the wireless device. Alternatively, the UICC fails when multiple operator networks are to be supported or accessed simultaneously within one device. Methods to update or change mobile network and service subscriptions are limited with SIM cards, and are generally lacking, when over-the-air deployment is desirable. Furthermore, though the SIM card or UICC is generally considered to be highly secure, this security is not linked strongly to security properties of the whole device on which it resides. This limits the application of scaling security concepts for advanced services and applications such as mobile financial transactions. All of these problems are imminent for autonomous devices connected to mobile networks for instance in machine-to-machine (M2M) communication scenarios. Accordingly, a more dynamic and concurrently secure software based solution to the SIM function is needed. A mobile trusted platform (MTP) configured to provide virtual subscriber identify module (vSIM) services is disclosed. In one embodiment the MTP includes: a device manufacturer-trusted subsystem (TSS-DM) configured to store and provide credentials related to a manufacture of the MTP; a mobile network operator-trusted subsystem (TSS-MNO) configured to store and provide credentials related to a mobile network operator (MNO); and a device owner/user-trusted subsystem (TSS-DO/TSS-U) configured to store and provide credentials related to user of the MTP. The TSS-MNO includes a vSIM core services unit, configured to store, provide and process credential information relating to the MNO. The TSS-DO/TSS-U includes a vSIM management unit, configured to store, provide and process credential information relating to the user of the MTP. The TSS-DO/TSS-U and the TSS-MNO communicate through a trusted vSIM service. Optionally, the MTP may separate the device user and device owner function into a TSS-DO and TSS-U and may include a second TSS-U configured to store and provide credentials relating to a second user of the MTP. Also, the MTP may include a device owner-trusted subsystem (TSS-DO) configured to store and provide credentials related to an owner of the MTP. The MTP may also include a second MNO-TSS configured to store and provide credentials related to a second MNO. Also disclosed is a procedure for remotely creating a trusted subsystem for use in providing vSIM services. Also disclosed is a procedure for registering and enrolling a trusted subsystem for use in providing vSIM services. Also disclosed is a procedure for delivering a trusted subsystem for use in providing vSIM services from a remote location to an MTP. Also disclosed is a procedure for migrating a trusted subsystem for use in providing vSIM services from a source MTP to a target MTP. Also disclosed are three related methods for allowing a subscriber using a vSIM configuration to access a wireless network.
